Dan looks very focused yet relaxed, less of the nervous tension I've seen previously.
I think this is an extremely salient point. The Evo on court is still the same guy, you still get the sarcastic banter and the self criticism but it has been dialled down to the point where it no longer has a negative impact. He looks like he is in control of his emotions and using then to his benefit rather than being controlled by them. He always operated on a fine line between playing well when angry and self destructing through irrational rage, he finally seems to have been able to harness the former without succumbing to the latter.
